Abstract

We undertake a step-by-step approach in the design of two Near Field Communication (NFC) products for pervasive healthcare monitoring. Our first product is an NFC based battery charger circuit to charge a thermometer equipped with wireless communication. Our system design has a simple linear charger, with overvoltage and under voltage protection implemented as an android App. The NFC power source provides 13 -- 15 mW of continuous power and is able to charge a 45mAH battery in about 10 hours from deep discharge to full charge state. Since the weight of the charger is about 3 grams and the size is about 2 cms in diameter, this product is useful for wearable sensor devices and provides a convenient way of recharging the batteries without the need for any connectors in the device. This allows devices to be hermetically sealed, besides enabling smaller form factors. The second product is an NFC based battery-less medical grade thermometer. To obtain the temperature of a single patient, a maximum of 10 seconds is sufficient to read the sensor value starting from placement of a smartphone over the product.
用于普及医疗保健监控的NFC
我们采用循序渐进的方法设计两种用于普及医疗保健监测的近场通信(NFC)产品。我们的第一个产品是基于NFC的电池充电器电路,可以为配备无线通信的温度计充电。我们的系统设计有一个简单的线性充电器,作为android应用程序实现过压和欠压保护。NFC电源提供13 - 15 mW的连续功率,能够在大约10小时内从深放电到充满电状态为45mAH电池充电。由于充电器的重量约为3克,直径约为2厘米,因此该产品适用于可穿戴传感器设备,并提供了一种无需设备内任何连接器即可为电池充电的便捷方式。这使得设备是密封的,除了可以实现更小的外形。第二款产品是基于NFC的无电池医疗级温度计。为了获得单个患者的温度,从将智能手机放置在产品上开始,最多10秒就足以读取传感器值。
